Which organ is most affected by chronic uncontrolled hypertension?

Chronic uncontrolled hypertension primarily impacts the heart due to the increased workload placed on this vital organ over time. When blood pressure remains consistently high, the heart must exert more effort to pump blood effectively throughout the body. This can lead to multiple cardiovascular issues, such as left ventricular hypertrophy, where the heart muscle thickens in response to the heightened demands.

In addition, prolonged high blood pressure can contribute to the development of various forms of heart disease, including coronary artery disease, heart failure, and arrhythmias. The relationship between hypertension and these conditions illustrates how the heart is particularly vulnerable to the effects of sustained elevated blood pressure, making it the organ most affected in this context.

While the kidneys and other organs can also be impacted by hypertension, the heart is at the forefront due to its central role in circulation and the direct consequences of increased blood pressure on its structure and function.
